Windows Live Sync is a free service designed to help you synchronize files across all the computers you use, share files and photos with friends and colleagues, and remotely access your files from any other computer connected to the Internet. If you have more than one computer, you can create personal folders to synchronize files between them. You can also share files with friends or colleagues when you create or connect your computer to a shared folder. Recently, the file synchronization application received support on Apple’s latest Mac OS X version.

You must install the Sync software from the Sync website, on every computer that you want to synchronize files on. You use the software to synchronize, share, and download files from a folder and to access the Sync website. The Sync software works in the background when you’re online and recognizes when files are changed, added to, or deleted from a synchronized folder. As you update files in a synchronized folder, Sync automatically updates files on the other online computers that synchronize with the folder.
